New Features

•Use the IP Addresses feature to assign an IP address to the integrated wireless LAN controller on the Catalyst 3750G-24WS-S25 and 3750G-24WS-S50 switches.

•Access the command-line interface (CLI) through the Telnet feature. It is available on the feature bar and on device popup windows in the Topology view and Front Panel view.

•Create communities with an unlimited number of access points.

•Use colors to highlight VLAN links in the Topology view. This option is available only if you are managing a community. To access it, you open Topology Options window and use the Highlighting tab.

•Print windows in a report format. In this format, none of the window information is truncated, as can happen if you use the PrtSc key to print the screen. The report format is also time-stamped, and pages are numbered.

•Print the Topology view or the Front Panel view in a fit-to-page format.

•Launch the device manager for devices in your network from device popup windows in the Topology view or Front Panel view.

•Stop the process of discovering neighbors at any point when you create or modify a community.

Note The Topology view of Network Assistant supports Catalyst 6500 switches. You cannot add these devices to a community or cluster, but you can launch device manager for them from the Topology view.

Access Points

Cisco Aironet 350, 1100, and 1200 series. Network Assistant supports them only if they run a Cisco IOS image.

Firewalls

Cisco PIX 515E Firewalls. PIX Firewalls do not support the Cisco Discovery Protocol, so they are not automatically shown as neighbors in the Topology view. They are shown only after you add them to a community by using a Create Community or Modify Community window. To see a PIX Firewall link to another community member, you must add the link manually by selecting Add Link in a Topology popup menu.

Cluster Compatibility

This section describes how to choose command and standby command devices when a cluster consists of a mixture of Catalyst switches. When creating a device cluster or adding a devices to a cluster, follow these guidelines:

•When you create a device cluster, we recommend configuring the highest end device in your cluster as the command device.

•If you are managing the cluster through Network Assistant, the device that has the latest software release should be the command device.

•The standby command device must be the same type as the command device. For example, if the command device is a Catalyst 3750 switch, all standby command devices must be Catalyst 3750 switches.

Limitations and Restrictions

You should review this section before you begin working with the device. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the device hardware or software.

Cluster Limitations and Restrictions

•By default, clustering is disabled on the Catalyst 4500 series switches.

•You must assign an IP address to the Catalyst 4500 series switch if it is a cluster command switch candidate. If the switch is a cluster member candidate, you might not need to assign an IP address.

•By default, the HTTP server is disabled on the Catalyst 4500 series switch. To connect the switch to Network Assistant, you must enable the HTTP server on all cluster members.

•The HTTP port number on Network Assistant and the Catalyst 4500 series switch must match.

•A Catalyst 4500 switch can be a cluster member only if another Catalyst 4500 switch is the command device.

•By default, the Catalyst 4500 series switch is configured with five vty lines. If the switch (such as a cluster command device with multiple cluster members) is connected to Network Assistant, you must configure at least eight + x vty lines, where x is the number of vty lines used by other applications. A maximum of 16 vty lines can be configured.

•Create a switch virtual interface (SVI) to use for intracluster communication. The SVI must be in the no shut state.

This limitation applies only to the Catalyst 4500 series and Catalyst 3750, 3560, 3550, and 2970 switches:

•If a Catalyst 2900 XL or 3500 XL cluster command device is connected to a Catalyst 3550 or a 3750 switch, the command device does not find any cluster candidates beyond the 3550 or the 3750 switch candidates. You must add the 3550 or the 3750 switch to the cluster to see other cluster candidates. (CSCdt09918)

These limitations apply only to the Catalyst 3750, 3560, 3550, and 2970 switches:

•If both the active command device and the standby command device fail at the same time, the cluster is not automatically recreated. Even if there is a third passive command device, it might not recreate all cluster members because it might not have all the latest cluster configuration information. You must manually recreate the cluster if both the active and standby command devices simultaneously fail. (CSCdt43501)

•When the active device fails in a device cluster that uses Hot Standby Routing Protocol (HSRP) redundancy, the new active device might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the Spanning Tree Protocol (STP) blocking state. See the "Configuring STP" chapter in the software configuration guide for more information about verifying port status. (CSCec31495)

These limitations apply only to the Catalyst 2955, 2950, and 2940 switches:

•When a cluster of devices have Network Time Protocol (NTP) configured, the command device is not synchronized with the rest of the devices. (CSCdz88305)

Network Assistant Limitations and Restrictions

The Network Assistant limitations and restrictions are described in these sections.

All Devices

•CNA supports the standard ASCII character set. Do not enter characters from extended ASCII character sets in GUI fields for feature options.

•A red border appears around the text-entering area of some Network Assistant windows. The color of the border changes to green when text is entered. The colored border does not prevent you from entering text. (CSCdv82352)

•You cannot switch modes (for example, from guide mode to expert mode) for an open Network Assistant window. The workaround is to close the open window, select the mode that you want, and then reopen the Network Assistant window. For the mode change to take effect on any other Network Assistant window that is open, you need to close that window and then reopen it after you select the new mode. (CSCdw87550)

•If you open a window in which you can enter text, open another window, and return to the first window, right-clicking in the text field might make the cursor in this field disappear. You can still enter text in the field. (CSCdy44189)

•If you select multiple ports and open the Port Settings window from the popup menu of the Front Panel view, it might take approximately 7 seconds to open.

The workaround is to open the Port Settings window from the feature bar. (CSCee96650)

•When the active device fails in a device cluster that uses HSRP redundancy, the new active device might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the STP blocking state. See the "Configuring STP" chapter in the software configuration guide for information about verifying port status. (CSCec31495)

•When there are more than one neighbor devices of same device type and they have same hostname, the Topology view displays only one neighbor device instead of displaying all the neighbor devices.

The workaround is to not have same hostname for more than one device. (CSCsb50280).

Catalyst 4500 Series Switches

On Catalyst 4500 series switches, Network Assistant supports only the features shown in Table 2:

•In Network Assistant, some windows such as VLAN, Hostname, and so on might not open from the Front Panel view popup menu for Catalyst 4500 series switches.

The workaround is to close Network Assistant and restart it. (CSCef67553)

Community Limitations

These limitations apply only to communities:

•A community can contain up to 20 devices. This limit is enforced whenever you add devices to a community.

Furthermore, a community cannot contain more than 16 nonmodular switches, 4 modular switches, and 2 routers. These limits are checked during the launch of Network Assistant; you receive a warning if they are exceeded.

•Changes to the topology or network do not propagate across all open Network Assistant sessions connected to the same community. You see this inconsistency when multiple Network Assistant sessions are open on one desktop, and they point to the same community.

Open one Network Assistant session per desktop per community. (CSCeh53619)

•In the Topology view, the horizontal scrollbar sometimes does not scroll far enough left to show the complete topology. The workaround is to right-click the Topology view and to select Automatic Topology Layout from the popup menu. (CSCeh56952)

•In the Topology view, if there are multiple links between community members and one of the links is blocked, it is shown in green, not in gray. There is no workaround. (CSCeh60050)

•In the Topology view, the redundant link for an HSRP group is not shown. There is no workaround. (CSCeh54526)

•If a community has members that are connected to a member through a hub or a Gigastack module, the Topology view shows all the connections. But if nonmembers are connected to a community member through a hub or a Gigastack module, the Topology view shows only the connection of the first nonmember.

•Accessing a community through a router running NAT (Network Address Translation) is not supported.

Cluster Limitations

These limitations apply only to clusters:

•When you add a new member with a username and password that is different from the existing cluster member usernames and passwords, Network Assistant produces an exception error because of an authentication failure.

The workaround is to add the new member without a username and password. When the new member is added to the cluster, remove the existing username and password from the Username and Password fields, enter a new username and password, and then apply it to all cluster members. (CSCdz07957)

•Changing the password or current authentication while Network Assistant is running causes HTTP requests to fail.

The workaround is to close all Network Assistant sessions and then to restart it. (CSCeb33995)

•When TACACS authentication is enabled only on a command device, member devices cannot be configured.

The workaround is to enable TACACS authentication on the member devices. (CSCed27723)

•When there are Catalyst 2950 and 2955 devices in a cluster, and you launch the QoS Queue window to configure the devices, and then try to view the settings for other devices by using the device selection menu, Network Assistant halts after 20 to 30 selections.

The workaround is to close and then to restart Network Assistant. (CSCed39693)

•A Java exception error occurs when Network Assistant is in read-only mode and you launch the Port Settings window. This only occurs on Catalyst 3500 XL, 2950 LRE, and 2900 XL switches.

The workaround is to open the Port Settings window with Network Assistant in read-write mode. (CSCee25870)

•After a cluster member loses connectivity, the connect icon in the status bar incorrectly displays a connect status instead of a disconnect status.

There is no workaround. (CSCee93695)

Community and Cluster Limitations

These limitations apply to both communities and clusters:

•Network Assistant fails when a device is running the cryptographic software image and the vty lines have been configured with the transport input ssh and line vty 0 15 global configuration commands to use only SSH. The workaround is to use the transport input ssh telnet and line vty 0 15 global configuration commands to allow SSH and Telnet access through the vty lines. (CSCdz01037)

•When the Link Graphs application has run for hours displaying packet drop and error information, sometimes the X-axis crosses the Y-axis at a negative Y value instead of at Y= 0. This condition occurs with all supported operating systems, browsers, and Java plug-ins. There is no workaround. (CSCdz32584)

•When you enable log scaling for Link Graphs, the Y-axis scale becomes illegible. There is no workaround. (CSCdz81086)

•If an access control list (ACL) is deleted from a device, all QoS classes on Catalyst 2970 and 3750 switches that use this ACL for traffic classification become unusable. The modification of these classes to use any other traffic classification (match statement) fails. The workaround is to delete the QoS class that uses the undefined ACL and then to recreate it with the intended traffic classification (match statement). (CSCed40866)

•When an Open Shortest Path First (OSPF) summary address is added for a 10.x.x.x network, a Windows exception error sometimes occurs.

The workaround is to add the address by using the router ospf <process-id>, area <area-id>, and range <address> <mask> configuration commands. (CSCed87031)

•Hostnames and Domain Name System (DNS) server names with commas for a cluster command device, member device, or candidate device can cause Network Assistant to behave unexpectedly. You can avoid this instability in the interface by not using commas in hostnames or DNS names. Do not enter commas when also entering multiple DNS names in the IP Configuration tab of the IP Management window in Network Assistant.

•Access control entries (ACEs) that contain the host keyword precede all other ACEs in standard ACLs. You can reposition the ACEs in a standard ACL with one restriction: No ACE with the any keyword or a wildcard mask can precede an ACE with the host keyword.

•If Network Assistant loses IP connectivity to the switch and an action is performed in the IP Address window, a Java exception error occurs.

The workaround is to close and to reopen the IP Address window when connectivity is restored. (CSCee91784)

•When you reload a device with Network Assistant, it saves the running configuration. If you want to reload without saving the running configuration, use the CLI. (CSCeh24259)

•If a dual-media port on a Catalyst 4500 switch, model WS-C4948 or model WS-X4506-GB-T, is configured to RJ-45 and you apply a Smartports port role, the port is changed to SFP, the default setting. The connection to the port is lost.

Reconfigure the media type to RJ-45 through the Port Settings window. (CSCeh31699)

•If you open the Modify Port Settings or the Modify Port Mode window twice in succession from the Front Panel view by right-clicking a port, selecting Port Settings or VLAN from the popup menu, and repeating these actions for another port, the windows display the settings for the port that you selected first.

Ensure that the Interface field in these windows applies to the port that you selected. Be sure to close these windows between port selections. (CSCei17154)

•After you perform a search, the TAB key moves the focus in the search results. If you press the TAB key enough to reach the end of the results, the next TAB keystroke moves the focus out of the search results and into the next-in-focus window on the Network Assistant desktop.

Press ALT-s to return to the search results. (CSCei68648)

•Network Assistant does not verify if the VLAN and the native VLAN are the same on the access point and the switch port that is connected to the access point. VLAN differences might cause wireless connectivity problems when you use the Secure Wireless feature.

The workaround is to ensure that the VLANs and the native VLAN are the same on the access point and the switch port. (CSCsb77434)

Community Notes

All the devices for the topology of a community are derived from the CDP (Cisco Device Protocol) table of Cisco IOS. Therefore, the Topology view shows duplicate devices when CDP discovers duplicate devices. This happens for a single device when the command show cdp neighbor is entered. Two devices are displayed: one with the actual hostname (for example, abc), the other with hostname.domainname (for example, abc.cisco.com).

Cluster Notes

This note applies to cluster configuration only on the Catalyst 3550 switches:

The cluster setup privileged EXEC command and the standby mac-address interface configuration command have been removed from the command-line interface (CLI) and the documentation because they did not function correctly.

Network Assistant Notes

•If you use Network Assistant on Windows 2000, it might not apply configuration changes if the enable password is changed from the CLI during your Network Assistant session. You have to restart Network Assistant and enter the new password when prompted. Platforms other than Windows 2000 prompt you for the new enable password when it is changed.

•Network Assistant does not display QoS classes that are created through the CLI if these classes have multiple match statements. When using Network Assistant, you cannot create classes that match more than one match statement. Network Assistant does not display policies that have such classes.

•Within an ACL, you can change the sequence of ACEs that have the host keyword. However, because such ACEs are independent of each other, the change has no effect on the way the ACL filters traffic.

•In the Front Panel view or Topology view, Network Assistant does not display error messages in read-only mode for these devices:

In the Front Panel view, if the device is running one of the software releases listed previously, the device LEDs do not appear. In Topology view, if the member is an LRE switch, the CPE devices that are connected to the switch do not appear. The Bandwidth and Link graphs also do not appear in these views.

Open Caveats

These sections describe the open caveats that could create possibly unexpected activity in this software release.

If a Catalyst 2970 switch is a cluster command device and a Catalyst 3750 or 3550 switch is a cluster member, enabling IGRP on a network on the Catalyst 3750 or 3550 switch creates a Premature EOF error.

There is no workaround. Make the Catalyst 3750 or 3550 switch the command device.

After you click Finish, you see the commands that are actually applied to the device.

•CSCeh32160

If you change a hostname while a Network Assistant window is open, the window might not display the new hostname, even if you refresh the window.

To see the new hostname, close the window and then reopen it.

•CSCeh37933

The Media Type column in the Port Settings window appears even if the modules of a Catalyst 4500 switch do not support AWP (alternate wired ports). If this case, the column fields display as N/A.

There is no workaround. The other columns in the window are not affected.

•CSCeh43889

In the Port Settings window, you must apply a change to some speed settings before you can change a duplex setting.

After you configure a speed setting, click Apply; then configure a duplex setting.

•CSCeh54393

In a Topology view for a community, the link icons for routed, trunk, and Gigastack links are not shown.

There is no workaround.

•CSCeh59451

Even if you see the message Port security is only supported on static access interfaces, it is also supported on ISL trunk ports and IEEE 802.1Q trunk ports if these ports are supported by the Cisco IOS image.

The Port Security window lists all the ports that are eligible for port security. If a port is not listed, configure the port as necessary through the VLAN window, and return to Port Security window to configure the port security settings.

•CSCeh72079

When the media type is changed on a S-X4506-GB-T linecard through the CLI or through another instance of Network Assistant, your instance of Network Assistant might be put into an inconsistent state, resulting in a blank Port Settings window.

The workaround is to close your instance of Network Assistant and then restart it. You can then use the Port Settings window without a problem.

•CSCeh75133

You cannot see the PoE columns in the Port Settings window for Catalyst 4503, 4506, or 4507R switches that run Cisco IOS 12.2(20)EWA and have a WS-4548, WS-4524, or WS-4506-GB-T PoE line card.

The workaround is to upgrade the software on the switch to a later version of Cisco IOS.

•CSCej02776

Zooming in or zooming out on the time axis of a bandwidth graph when the axis approaches noon or midnight might cause the time increments to be incorrectly labeled.

Close the Bandwidth Graph window, reopen it, and zoom in or out again.

•CSCsb77153

On Catalyst 4500 and 4900 series switches, you cannot edit flow control values from the Port Settings window; they are read-only.

The workaround is to open the Front Panel view, right-click on the port to be configured, and select Port Settings from the drop-down list. From the Modify Port Settings window, you can configure the flow control values.

•CSCsb88555

On a Catalyst 4500 or Catalyst 4900 series switch, when you select Security > Port Security and try to associate a secure address with a trunk port, an "Invalid input detected" error is displayed.

There is no workaround for a trunk port. Open the VLANs window, select the device and port, click Modify, and select an administrative mode that is not for a trunk port.

•CSCsb88566

When you connect to Network Assistant in read-only mode, choose Configure > Port > Port Settings on the feature bar, and select a Catalyst 4500 series switch, you are prompted to request level-15 access. This is the read/write access level, which is incompatible with read-only mode. You cannot view the Port Settings window.

The only workaround is to get permission from your administrator to connect to Network Assistant in read/write mode.

•CSCsd64494

For a stack of Catalyst 3750 switches, the Hostname list in the Bandwidth Graphs window has an entry for an entire stack and for each of the devices in the stack. The window shows valid data only for the entire stack.

There is no workaround. Ignore the data that is shown for stack members.

•CSCsd80600

When you open the Modify Port Settings window from the Front panel view and change the duplex, speed, or power (PoE switches only) setting, the old setting is shown when you close the window and open it again. The Port Settings window and command-line interface do show the change.

The change appears in the Modify Port Settings window if you click the Refresh icon on the toolbar.

•CSCse58716

In the Bandwidth Graphs window of the Spanish version of Network Assistant, the legend label Bandwidth Utilization is cut off on the right.

Enlarge the window to see the full label.

•CSCse80505

In non-English versions of Network Assistant, the letter bar at the top of the glossary contains some letters for which there are no corresponding glossary entries. Clicking these letters takes you to the bottom of the glossary. In the Japanese and Chinese versions, the glossary bar does not contain Chinese and Japanese characters.

You can find Japanese and Chinese terms by browsing the glossary.

•CSCsf09989

When you scroll from right to left in a text field, the far left characters are sometimes cut off.

There is no workaround.

These caveats apply to Cisco EtherSwitch service modules:

•CSCei55046

The Front Panel view on EtherSwitch service modules NME-16ES-1G-P, NME-X-23ES-1G-P, NME-XD-24ES-1S-P, and NME-XD-48ES-2S-P shows the EN-LED as not enabled.

There is no workaround.

•CSCsd04956

The Topology view does not show the internal Gigabit Ethernet link between routers and the EtherSwitch service modules NME-16ES-1G and NME-X-23ES-1G.

There is no workaround.

•CSCsd06275

The Smartports window shows the NME-XD-24ES-1S-P EtherSwitch service module with two Mode buttons instead of one

There is no workaround.

Resolved Caveats

This section describes the resolved caveats.

Caveats Resolved in Network Assistant 4.1

This caveat was resolved in Network Assistant 4.1:

•CSCse65622

You can now manage Cisco 870 Series Integrated Services Routers, models 871 and 877W, in communities.

Caveats Resolved in Network Assistant 4.0

These caveats were resolved in Network Assistant 4.0:

•CSCeh17771

Access points and routers are not supported in the Front Panel view. Their check boxes are grayed out and now do not appear with a check mark.

•CSCei78959

If you set the configuration bits through the CLI to 0x2100 or 0x2101 and then restore a configuration with the Configuration Archive window, you can now reload the device.

•CSCej00845

If a device has multiple IP addresses and more than one of these IP addresses is added to a community, the device is now counted only once in determining whether the community limits have been exceeded.

•CSCsb60066

If you change the hostname of a community member in a Network Assistant session and change it in a session with a different community, you no longer see a message that the name change failed.

•CSCsb90846

Upgrading the Cisco IOS software on a device to a cryptographic image from an noncryptographic image is now sufficient to make an HTTPS connection with the device.

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
